ports: Make new ports/ sub-directory and move all ports there.

This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.

-MicroPython port to ESP8266
-===========================
-
-This is an experimental port of MicroPython for the WiFi modules based
-on Espressif ESP8266 chip.
-
-WARNING: The port is experimental and many APIs are subject to change.
-
-Supported features include:
-- REPL (Python prompt) over UART0.
-- Garbage collector, exceptions.
-- Unicode support.
-- Builtin modules: gc, array, collections, io, struct, sys, esp, network,
-  many more.
-- Arbitrary-precision long integers and 30-bit precision floats.
-- WiFi support.
-- Sockets using modlwip.
-- GPIO and bit-banging I2C, SPI support.
-- 1-Wire and WS2812 (aka Neopixel) protocols support.
-- Internal filesystem using the flash.
-- WebREPL over WiFi from a browser (clients at https://github.com/micropython/webrepl).
-- Modules for HTTP, MQTT, many other formats and protocols via
-  https://github.com/micropython/micropython-lib .
-
-Work-in-progress documentation is available at
-http://docs.micropython.org/en/latest/esp8266/ .

-Build instructions
-------------------
-
-The tool chain required for the build is the OpenSource ESP SDK, which can be
-found at <https://github.com/pfalcon/esp-open-sdk>.  Clone this repository and
-run `make` in its directory to build and install the SDK locally.  Make sure
-to add toolchain bin directory to your PATH.  Read esp-open-sdk's README for
-additional important information on toolchain setup.
-
-Add the external dependencies to the MicroPython repository checkout:
-```bash
-$ git submodule update --init
-```
-See the README in the repository root for more information about external
-dependencies.
-
-The MicroPython cross-compiler must be built to pre-compile some of the
-built-in scripts to bytecode.  This can be done using:
-```bash
-$ make -C mpy-cross
-```
-
-Then, to build MicroPython for the ESP8266, just run:
-```bash
-$ cd esp8266
-$ make axtls
-$ make
-```
-This will produce binary images in the `build/` subdirectory. If you install
-MicroPython to your module for the first time, or after installing any other
-firmware, you should erase flash completely:
-
-```
-esptool.py --port /dev/ttyXXX erase_flash
-```
-
-Erase flash also as a troubleshooting measure, if a module doesn't behave as
-expected.
-
-To flash MicroPython image to your ESP8266, use:
-```bash
-$ make deploy
-```
-This will use the `esptool.py` script to download the images.  You must have
-your ESP module in the bootloader mode, and connected to a serial port on your PC.
-The default serial port is `/dev/ttyACM0`, flash mode is `qio` and flash size is
-`detect` (auto-detect based on Flash ID). To specify other values, use, eg (note
-that flash size is in megabits):
-```bash
-$ make PORT=/dev/ttyUSB0 FLASH_MODE=qio FLASH_SIZE=32m deploy
-```
-
-The image produced is `build/firmware-combined.bin`, to be flashed at 0x00000.
-
-__512KB FlashROM version__
-
-The normal build described above requires modules with at least 1MB of FlashROM
-onboard. There's a special configuration for 512KB modules, which can be
-built with `make 512k`. This configuration is highly limited, lacks filesystem
-support, WebREPL, and has many other features disabled. It's mostly suitable
-for advanced users who are interested to fine-tune options to achieve a required
-setup. If you are an end user, please consider using a module with at least 1MB
-of FlashROM.
-
-First start
------------
-
-__Serial prompt__
-
-You can access the REPL (Python prompt) over UART (the same as used for
-programming).
-- Baudrate: 115200
-
-__WiFi__
-
-Initially, the device configures itself as a WiFi access point (AP).
-- ESSID: MicroPython-xxxxxx (x’s are replaced with part of the MAC address).
-- Password: micropythoN (note the upper-case N).
-- IP address of the board: 192.168.4.1.
-- DHCP-server is activated.
-
-__WebREPL__
-
-Python prompt over WiFi, connecting through a browser.
-- Hosted at http://micropython.org/webrepl.
-- GitHub repository https://github.com/micropython/webrepl.
-
-Please follow the instructions there.
-
-Documentation
--------------
-
-More detailed documentation and instructions can be found at
-http://docs.micropython.org/en/latest/esp8266/ , which includes Quick
-Reference, Tutorial, General Information related to ESP8266 port, and
-to MicroPython in general.
-
-Troubleshooting
----------------
-
-While the port is in beta, it's known to be generally stable. If you
-experience strange bootloops, crashes, lockups, here's a list to check against:
-
-- You didn't erase flash before programming MicroPython firmware.
-- Firmware can be occasionally flashed incorrectly. Just retry. Recent
-  esptool.py versions have --verify option.
-- Power supply you use doesn't provide enough power for ESP8266 or isn't
-  stable enough.
-- A module/flash may be defective (not unheard of for cheap modules).
-
-Please consult dedicated ESP8266 forums/resources for hardware-related
-problems.
